NON-REFILLABLE BOTTLE,

Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed October 6, 1913. Serial No. 793,505.

To all whom it may concern a Be it known that we, SAMUEL R. Jorrn, NATHAN Jorrn, and LOUIS F. MAHLE, of the city of'Rochester, in the 'county of Monroe and State of New York, have invented certain new and useful Improvements in Non-Refillable Bottles; and we do hereby declare the following to be a full, clear, and exact-description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon..

Our present invention relates to non-refillable bottles and it has for its object to provide a simple, cheap and practical device of this character, which will be efficient in use, but which 'may be manufactured by ordinary processes familiar to the art, whereby the usual prohibitive expense incident to the commercial production of many devices of'this kind will be obviated. A further object of the invention is to provide a ,check'valve mechanism of such sensitiveness that the valve or stopper will assume its closed position even when the bottle neck is in a substantially horizontal position whereby a pronounced tilting movement is required to unseat it with the bottle held at such an angle as to make refilling in that position practically impossible.

Our invention is also directed toward providing means for sealing the bottle and the outer stopper or cork thereof by a simple expedient combined with the structure producing the non-refilling functions.

To these and other ends the invention consists in certain improvements and combinations of-parts, all as will be hereinafter more fully described, the novel features be ing pointed out in the claims .at the end of the specification. 4

-In the drawings Figure -1 is a vertical central vsection'through a bottle neck and stopper mechanism constructed in accordance-with and illustrating: one embodiment of our invention, the parts being shown in their normal positions, whichare the posithe bottle is up relative, positions of the 9 parts when the bottle is tilted 'for thepurpose of pouring out the contents; Fig. 3is a similar view showingthe relative positions ofthe parts when thebottle is held with the neck substautiallv hcn'izontal; Fig. .595, is abottom plan view of the upper portion or cap piece of the neck, and Fig: 5 is atop plan View of the device.

Similar reference numerals throughout the several figures indicate the same parts.

In the practice of our invention the lower or body portion 1 of the neck may be formed in substantially the same manner as the neck proper of an ordinary bottle with a slightly rounded or flaring mouth which, in the present instance, constitutes a seat 2 for the stopper valve hereinafter described. Resting on the neck is a cup-shaped cap piece or upper neck portion 3 having a restricted mouth or discharge opening lclosed by an outer stopper 5 provided with a head 6. The lateral and top walls of the portion 3 are preferably provided with ribs 7 and 8 that leave open channels between them for the flow of liquid even though other bodies may be resting against them, as will later appear.

A suitable gasket 9 is preferably interposed between the two portions of the neck to form a liquid-tight jointand they are rigidly held together by spinning upon or otherwise applying to the exterior an encircling band or collar 10 which spans the joint 9, is flanged over upon the top shoulder of the cap piece 3 and which interlocks at the bottom with a suitable ridge or other irregularitiy 11 formed. on the exterior of the lower neck portion 1. The parts inclosing the stopper valve mechanism hereinafter described are thus held securely together and at the same time we utilize the band 10 for sealing the bottle as a whole by passing a seal strip 12 over the head 6 of the outer stopper 5 and securing the ends beneath the band in the manner clearly shown in Fig. 1. To open the bottle, therefore, in the first instance it is necessary to break this strip 12 which can readily be done along the line indicated at 13 in Figs. 2 and 3, which show the bottle uncorked.

The stopper valve 14 may be substantially semi-spherical in form, as shown, and comprises an upper hollow enlarged portion 15 that normally occupies and seals the seat 2- and a lower approximately solid reduced portion 16, smaller in diameter than the seat, and preferably having an excess of material 17 that provides a weight at the lower end of the stopper. With the bottle upright, this, weight, of course, tends to hold the enlarged portion in firm engagement with theseat 2. 'While in this position it might be possible to raise the stopper valve by grippingits top edge or its hollow interior with a suitable tool or instrument inserted through the discharge opening 4, and to prevent this we provide a detached and relatively movable cover piece in the present form of a fiat disk 18 which normally rests upon and incloses the open side .of the stopper, and the upper surface of which is preferably smooth and regular to prevent even it from being gripped easily. .This cover piece, therefore, prevents access to the stopper and if it were raised through some instrumentality, as, for instance a suction gripper inserted through the discharge opening 4:, it would only serve to further close the latter and the stopper would be left secure in its proper position.

-lVhen the bottle is inverted or tilted to a pronounced angular position, as shown in Fig. 2, the stopper valve 14, of course, gravitates from its normal position so that its reduced portion 16 is opposite the seat 2 and becauseof the lesserdiameter of this reduced portion a passage for the liquid is left as shown. The ribs 7 and 8 provide further passageways between them to the mouth'4 by holding off the cap piece 18 from a close contact with the adjacent walls of the valve chamber, both .top and sides. When the bottle is held with its neck in a substantially horizontal position, which is the case during ordinary attempts to refill by submergeiiceand similar ways. the valve member 14 will still move to its closed position in coiiperation with the seat 2. as shown in full lines in Fig. 3, from the dotted line position of Fig. '3 and the full line position of Fig. 2. This happens by reasonof the fact that the rear or lower portion is heavier and the center of gravity is far to the left of the geometrical center. Thus. instead of remaining in the openposition of Fig. 2 with the enlarged portion 15 up against the cover piece 18, as shown-in dotted lines in Fig. 3. only the then lower edge of the en larged portion lies against the cap and with the reduced portion 16 lying against and closing one side of the seat 2, the other edge or side of the enlarged portion rotates backward into operative engagement with the other side of the seat. as a result of a tilttions shown, as will readily appear. give ood results and may be generally followed. The stopper must emerge from the seat a sufficient distance to provide a suitable passage for the liquid. but at the same time it must be checked from going so far that the fulcrum furnished by the contact of the re-,

ducedportion 16 with the seat, as shown in a Fig. 3, will not be on the wrong side of the center of gravity, and in the present iiistance, the cap piece 18 constitutes an abutment for. defining the extent of the unseat ing movement.

Attention is called to the fact that the practice of our present invention does not require unusual formations of the glass on the inside of the body portion 1 or neck proper of the bottle, as is required with most devices of the prior art, which formations are both expensive and impractical while the upper portion or cap piece 3 is small in size and simple in design rendering it easily molded or pressed into form and to be constructed from any one of a variety of materials. The parts are also easily assembled after the bottle has been filled by adjusting to their positions the stopper valve 14, the cap piece 18, the neck section 3, the stopper 5 and the seal strip 12, in the order named, and then spinning on or otherwise applying the band 10.

We claim as our invention:

1. In a non-refillable bottle, the combination with a neck having a seat, of a stopper valve embodying an upper enlargedportion normally occupying and sealing the seat and a lower reduced portion. the stopper being weighted at its lower end adapting it to tilt when the neck is held substantially horizontal and to rest with its reduced portion in contact with one side of the seat and, by such tilting, to bring the enlarged portion into operative relationship with the otherfrom emerging too far from the latter to effect the tilting action described.

2. In a. non-refillable bottle. the combina I tion with a neck having a seat, of a stopper valve embodying an upper enlarged portion normally occupying and sealing the seat and a lower reduced portion. the stopper being weighted at its lower end adapting it to tilt when the neck is held substantially horizontal and to rest with its reduced portion in contact with one side of the seat and. by such tilting. to bring the'enlarged portion into operative relationship with the other side of the seat and an abutment spaced from and arranged above the seat to prevent the reduced portion of the stopper from emerging too far from the latter to efiect the tilting action described. i

3. In a non-refillable bottle. the combination with a neck having a seat, of a stopper enlarged portion normally occupying and sealin the seat and a relatively heavier solid lower reduced portion adap 'iig the stopper to tilt when the heel; is held substantially horizontal and the stopper is resining with its reduced portion in Contact with one side of the seat and, by such tilting. to bring the enlarged portion into operative relationship with the other side of the seat, and a detached cover for the open top side of the hollow enlarged portion adapted to sale-Um R.
